Why is it so hard to create reliable long-range video/audio transmission? In today day and age, I think every piece of software in my smartphone or computer require more or less constant uninterrupted access to the Internet and it works almost flawlessly. But whenever I call my parents that are 500 kilometers away from me in a messenger app, we almost always have some interruptions, connection drops, etc. After certain recent events, I find a lot of my favorite bloggers move away to live in the different parts of the world, and when they try to have some joint episodes on Youtube, it happens almost always that somebody’s connection would drop for a minute or so. Why is it so easy to download stuff from American servers at 100 Mb/s being in Eastern Europe, but almost impossible to have uninterrupted video/audio connection over the same distance?

The key word is “uninterrupted”.
The constant access that your cell phone and smart devices have isn’t actually uninterrupted… it’s “always on” but interruptions are commonplace even if you never notice.
Same goes for downloads. Does the download come through at full-throttle for the entire download, or does the progress bar speed up and slow down sometimes mid-download? More often than not, it does have those speed-ups/slow-downs! Those are interruptions! You just don’t notice them!
The issue with **live** audio/video transmission is that all the delays/interuptions become noticeable, not that delays/interruptions are suddenly created.
